I’ll give you brain list if you answer this for me

131.9 cm

Step-by-step explanation:

Circumference = (2)(pi)(r)

radius = 21

pi = 3.14

c = (2)(3.14)(21)

c = 131.88

Round to the nearest tenth = 131.9

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.
